I have a LINQ to SQL class "VoucherRecord" based on a simple table. One property "Note" is a string that represents an nvarchar(255) column, which is non-nullable and has a default value of empty string ('').

If I instantiate a VoucherRecord the initial value of the Note property is null. If I add it using a DataContext's InsertOnSubmit method, I get a SQL error message:

Cannot insert the value NULL into column 'Note', table 'foo.bar.tblVoucher'; column does not allow nulls. INSERT fails.

Why isn't the database default kicking in? What sort of query could bypass the default anyway? How do I view the generated sql for this action?

Thanks for your help!

Ran into an odd behavior today with a many to many mapping of one of my tables in LINQ to SQL.

In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
